Carrilho, F.; Custodio, S.; Bezzeghoud, M.; Oliveira, C. S.; Marreiros, C.; Vales, D.; Alves, P.; Pena, A.; Madureira, G.; Escuer, M.; Silveira, G.Portugal, located in the southwest region of the Eurasian plate, has been affected by several destructive earthquakes throughout its history, the most well-known being the 1755 Great Lisbon earthquake. The seismicity of the territory, both in the mainland and in the Azores and Madeira islands, has prompted the continuous development of seis- mic monitoring, from the first known macroseismic inquiry, following t...
Improved three-dimensional image of the tomographic inversion of the Arraiolos ...
Hamak, I.; Wachilala, P.; Borges, J. F.; Dias, N. A.; Rio, I.; Bezzeghoud, M.This work puts in light the several steps followed to obtain a 3D velocity model in Arraiolos, a region located in central Portugal. After the earthquake of January 2018 occurred, a set of stations were deployed around the main shock area and has recorded the aftershock sequence during a period of six months. The first stage of this study used a set of data recorded along the 1st month by 21 temporary seismolog...

Hamak, I.; Wachilala, P.; Borges, J. F.; Dias, N.; Rio, I.; Bezzeghoud, MouradThis work presents the results obtained after the Arraiolos aftershock sequence tomographic inversion in terms of velocity th distribution. The study deals with the 4.9 ML magnitude earthquake (Mw4.3, Vales et al., 2018) which occurred on January 15 , 2018 at 11:51 UTC in Aldeia da Serra in the Northeast of Arraiolos (Alentejo, Portugal). The hypocentral location, determined by the Instituto Português do Mar e ...
